switch to a variable frequency clock at light loads, but retain the same method
of control.
Summary. Be very careful in selecting a control IC for your application!
3.9 Designing the Voltage Feedback Circuit
The only function of the voltage feedback loop is to hold the output voltage(s)
at a constant value. Complications arise in areas such as transient load response,
accuracy of the output(s), multiple outputs, and isolated outputs. All of these
individually can be nightmares for the designer, but if the design approaches
are understood then each factor can easily be satisfactorily addressed.
The heart of the voltage feedback loop is a high-gain operational ...
